Application filed April '7, 1902. Serial. No. 101,741. (No model.)

To (bl/1 (Uh 0H2, U3 Iii/0]] concern:

Be it known that I, 'lnnonon Iiunnrz, a citizen of the United States of America, residing at Cleveland, in the county of Guyahoga and State of ilhio, have invented certain new and useful Improvements in Machine- Bearing 'Cabines, end I hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the urt to which it pertains to make and use the same.

This invention relates to improvements in machine-bearing cabinets wherein a tilting leaf adapted to curry :1. sewing-nmchine head, type-writer, or other machine or mechanism is lowered below or occupies an opening in the top of the cabinet, according as the said leaf is in its downwardly-tilted position and upper and horizontal position.

This intention pertains more especially to novel and meritorious mechanism for operating the said load-bearing tilting leafv The objectof this invention is to provide a simple and inexpensive and reliable and convenient operative connection between the said load-bearing leaf and lifting lent which is hinged to the top of "he cabinet.

"With this object in VIEW the invention consists in certain features of construction and combinations of parts, hereinafter described, and pointed out in the claims.

In the accompanying drawings, FigureI is a front side elevation of the said improved machine-bearing cabinet. llig. II is a top plan of the same. Portions are broken away in Figs. I and II to reduce the of the drawings. Fig. III is enlarged top plan on line III III, I. IV is an end elevation, mostly in vertical section, on line IV IV, Figs. I and II, looking in the direction indicated by the arrow. Fig. V is an end elevation, mostly in vertical section and corresponding with Fl IV, except that in Fig. V the load-bearing leaf is shownin its downwardly tilted or depending position. Fig. VI is an enlarged section in detail, showing the attachment to the load-bearing leaf of the forward and upper portion of a bar instrumental in establishing operative connection The cabinet comprises a horizontally-arranged top a, which is provided, preferably centrally,witharectangular opening a,which extends vertically through the said top and accommodates the location and operation of the load-bearing leaf 5 of the cabinet, which leaf is pivoted horizontally, as at b, to the rear portion of the top a. The pivots b are shown arranged longitudinally of the cabinet in close proximity to the rear edge of the leaf 1). In Figs. I, II, and IV the leaf 1) is shown in its upper and horizontal position, and therefore occupying the opening in the top a. In Fig. V the leaf 1) is shown in its downwardly-tilted position, and consequently depending below the opening a, and the leaf b is actuated from its horizontal position (shown in Figs. I, II, and III) into its depending position,-(shown in Fig. V,) or vice versa, according as the sewing-machine head or other machine or mechanism (not shown) which the said leaf is adapted to bear is to be conveyed into the cabinet from outside the cabinet, or vice versa.

Aleaf c,which is shown hingedat one end,as ct c,to the top (t,horizontally and transversely of the cabinet at the left-hand side of the opening a, has the dimensions and arrangement required to render it capable of being swung over, and thereby closing the opening it, as shown in Fig. V, or forming an extension of the top CL, as shown in Figs. I and II, according as the said leaf is actuated into the one or the other of its extreme positions.

A novel and meritorious operative connection between the leaf 0 and the leaf b, whereby the latter is tilted downwardly or upwardly, according as the former is actuated over the opening a or moved to uncover the said opening, is provided and constitutes the subjectmatter of this application, and the'said operative connection comprises a. chain or cable 6, attached at one end, as at 6, (see Figs. I and 11,) to the leaf 0, near the rear edge of the said leaf. The cable 6 extends from the leaf 0 to and over a guide-sheave f, (see also Figs. IV and V,) which is supported from the rear portion of the top a rearward of the opening a and centrally between the ends of the said opening. The cable 0 leads downwardly from the sheave f and is attached at its lower end to a bail g, with which a vertically-movable slide is provided, which slide (see Figs. I, III, andV) comprises, preferably, a cylindrical section h, which is arranged horizontally and longitudinally between two stationary vertically-arranged and parallel slideway-forming bars k, with which the upright back Z of the cabinet is provided upon its forward side. The bars 70 are provided in their inner edges with verticallyarranged grooves it, which are engaged by correspondingly-arranged tongues h, formed upon the ends of the section It.

The leaf b is provided upon its under side, preferably centrally between its rear and forward edges, with two brackets N, which depend from opposite ends, respectively, of the said leaf and support a cylindrical bar m, which is arranged horizontally and longitudinally of the said leaf and preferably parallel or approximately parallel with the axial line of the leaf and, preferably, a suitable distance below the under side of the leaf to accommodate the extension of portions of the machine or mechanism (not shown) to be mounted upon and secured to the said leaf downwardly through and somewhat below the opening 12 with which the said leaf is provided.

A wooden brace-forming bar 1" is employed in establishing operative connection between the leaf 1) and the aforesaid slide and extends from the bar m downwardly and rearwardly to the said slide. The brace r is attached at its upper end to and centrally between the ends of the bar m bya metal strap 3, which-(see Figs. IV, V, VI, and VIII) straddles the bar m from above and engages an annular groove m, (see Figs. VI and VIII,) with which the said bar m is externally provided. Opposite end portions of the said strap 8 engage opposite sides, respectively, of the brace r, as shown in Fig. VI, and terminate in teeth 8, which project into and are embedded in the said brace. The end portions of the strap 8 are preferably also secured to the brace r by staples t.

The brace 1' has its forward and upper end snugly but turnably embracing, and consequently conforming to, the cylindrical contour of the bar m, so as to form a suitable bearing for the said end of the brace r and accommodate the oscillation or tilting of the said brace r upon the bar m during the actuation of the leaf 1) from one to the other ofits positions.

The brace r is attached at its lower and rear end to the slide-forming cylindrical section h by a metal strap u, which straddles the said section from below and engages an annular groove k (see Figs. III and VII,) with which the said section is provided centrally between its ends. Opposite end portions of the strap u engage and extend longitudinally of opposite sides, respectively, of the brace 7 and terminate in teeth 'u/,Which are embedded in the said brace, and the said end portions of the strap are preferably fastened also to the said brace by staples 00. The rear andlower end of the brace r embraces or extends circumferentially of and conforms to the cylindrical contour of the section h, so as to form a suitable bearing for the said brace upon the said section it and accommodate the oscillation or turning of the brace uponthe said section h during the operation .of the slide comprising the said section h.

The top a and the leaf 0 are suitably slotted or cut away, as at y, to accommodate'the location and operation of the cable 6 and the sheave f.

The arrangement of the parts is such that the leaf 0 when the leaf 1) is in its upper and horizontal position occupying the opening a is in a full open position, so as to form an extension of the top a, as shown in Fig. II, and the leaf b is in its downwardly-tilted or depending position when the leaf 0 is actuated into its closing position, so as to cover the said opening, that the leaf 1) is tilted downwardly or upwardly, according as the sliding section h is lowered or elevated, and that the said section h descends or ascends, according as the leaf b is actuated into its closing position or in the opposite direction.

It will be observed that the brace r when the leaf 5 is in its horizontal position participates in supporting and adequately braces the said leaf and any load required to be borne by the said leaf.
